| Abstract(in English) | We aim to construct a spoken dialogue system for multiple in-vehicle information system. It is necessary to recognize a domain and utterance correctly from the viewpoint of safety and immediateness under driving condition. We have proposed a method that predicts user's utterances by recognizing prediction sentences of each dialogue state based on discourse tags. However, it is difficult to recognize the domain and utterance in the spoken dialogue of multi-domain because there are a lot of dialogue states and prediction sentences. In this study, we propose a method using the prediction sentence and phoneme recognition. The method performs the phoneme recognition and compares the recognition result with the prediction sentence in all domain by DP matching and recognizes for prediction sentence candidates obtained by DP matching. We conducted experiments in multiple in-vehicle information system. As a result, recognition accuracy was 87.9% for prediction sentences in all domain and was 96.3% by the proposed method. Therefore, the proposed method was effective in the spoken dialogue of multi-domain. |
